[Ubuntu-x-swat] [Bug 428054] Re: xrandr backlight property control missing (when using KMS?)
Seems to me that this might be a mayor issue. I don't know how many people are affected but many people are buying notebooks with these intel graphic chips. Not being able to adjust brightness is a serious problem for usability.

The backlight property only shows up when using nomodeset.
